A model (abstract 0599) comparing the efficacy and compliance of current PROVENT Therapy data to continuous positive airway pressure (CPAP) data from the literature suggests that PROVENT Therapy may prevent a similar or greater number of apnea/hypopnea events as compared to CPAP when the therapies’ respective adherence rates are taken into account.²

This model analysis by Anne Abreu, Director of Reimbursement and Business Development at Ventus Medical, and colleagues, compared the effectiveness of PROVENT Therapy versus CPAP taking into consideration both apneas and hypopneas prevented during hours of use and those not prevented due to lack of use.

Results showed that PROVENT Therapy may prevent a similar or greater number of abnormal breathing events as compared to CPAP, based on the modeling scenarios. “This model demonstrates the importance of factoring in compliance rates when choosing a therapy for treating obstructive sleep apnea,” said Abreu.
